Grails 3 service not syntax highlighting HQL queries on domain object

In a grails 3 service it isn't syntax highlighting the HQL query like it used to in grails 2.5. Like when you do

Domain.executeQuery("from Domain where foo = :foo")

This particular project is multi module with a plugin and multi web apps which reference it. I haven't tried in a single module project

Start with the Grails 3 service example using Domain.executeQuery("from Domain where foo = :foo") and reproduce it in the reported multi-module project with a plugin and multiple web apps. Compare the behavior with Grails 2.5 and verify that the HQL string receives syntax highlighting; also check whether the issue reproduces in a single-module project.
